What is the super wolf blood moon?

An article on ABC News about this month’s super wolf blood moon, which will be visible throughout North America, especially on the eastern side of the continent, interviews Tracy Gregg, professor of geology, who discussed the extremely rare full lunar eclipse. “So a super blood wolf moon is: a) the first full moon in January; b) a full moon occurring when the distance between the Earth and Moon is as short as possible; c) a lunar eclipse -- all happening at once!” she said, adding that it is a rare phenomena that will appear only 28 times this century.
